yep the timing chain was really lose and was chewing thru that bolt head....
So I ordered a timing chain kit...
I got every thing pulled apart and was able to remover the bolt with half the head missing.
when I went to remove the hidden bold that connects the head to the timing chain cover, it was missing as in not installed
Had some issues getting the timing chain cover off with all of the RTV that was on it in and removing the crankshaft pulley and the pump drive spine, which put up a little bit of a fight coming off.
after removing the timing chain cover I was checking things out to see what damage there was and noticed that the timing chain no longer had any slack in it
and the tensioner was extended and holding the chain tight.... not sure what the deal was when the chain had all kinds of slack in it prior to removing the timing chain cover. I'm guessing the tensioner was stuck closed or partly closed.
There is a little bit of damage from when the chain was lose to the timing chain cover and the front of the head but I dont think its enough to worry about.
The distributor shaft had a lot of play on the top end and the springs seems to have no life left in them either, so I got a replacement distributor too.
